Shared Attribution

Per SB 216, the Ohio Teacher Evaluation System will change beginning with the 2020-2021 school year. Districts and schools, other than the limited number of districts participating in the voluntary pilot program, will continue to use the current OTES system for 2018-2019 and 2019-2020.

There will be no changes for 2018-2019 and 2019-2020 evaluations.


Shared attribution is defined as a student growth measure that can be attributed to a group. This measure can be used to encourage collaborative goals and may be used as data in the student growth component of teacher and principal evaluation. The Ohio Department of Education recommends careful consideration and collaboration regarding the use of shared attribution data for teachers of kindergarten through grade 12, as the intent of the new evaluation system is to capture the truest picture of an individual teacher’s impact on his or her student population.

Ultimately, the use of a shared attribution measure, including the percentage of weight designated within guidelines set in law, is a district decision. Student growth measures should collectively represent each individual teacher’s impact on student learning for his or her particular student population. Therefore, choosing to use shared attribution at any level should not be taken lightly.

The decision to use shared attribution according to a particular weight(s) should involve close consideration of individual district factors, as well as how the practice will promote collaboration and achieve consistency.

The department provides recommendations to assist districts with shared attribution decisions in this guidance document.
